NORMAN DODGE, OF EAST ORANGE, NEW JERSEY, ASSIGNOR TO MERGEN'IHALERLINOTYPE COMPANY, A CORPORATION OF NEW YORK.

TYPOGRAPHICAL MACHINE.

Specification of Letters Patent.

Application filed October 11, 1 911.

To all whom it may concern Be it known that I, NoRMAN DoDGE, a citizenof the United States, and a resident of East Orange,county of Essex, andState of New Jersey, have invented a new and useful Improvement inTypographical Machines, of which the following is a specification.

My invention relates to typographical machines, and more particularly tothat class thereof known to the public under the name linotype, and asdisclosed for instance in Letters Patent of the United States to O.Mergenthaler, No. 436,532, wherein circulating matrices are releasedfrom a magazine in the order in which their characters are to appear inprint and then assembled in line together with expanding spacers, thecomposed line transferred to the face of a mold, the mold filled withmolten metal to forma slug or linotype against the matrices whichproduce the type characters thereon and the matrices thereafter elevatedand returned through a distributing mechanism to the magazine from whichthey started. 1 1

The present improvements relate -more particularly to the means forassembling the line and for transferring it to the first ele-. vator,and also to the means whereby after casting the matrices are lifted tothe distributing mechanism. In other respects the parts and mode ofoperation are or may be substantially the same as those in the said Thepresent devices are designed to reverse the position of the matricesedge for edge after they have been released from the magazine and beforethey are delivered to the first or casting elevator, and similarly toreverse them again or restore them to their original position aftertheir removal from the casting elevator and before they are presented tothe distributor. Such reversing means generically are not novel, but sofar as I am aware, they have been previously employed to turn individualmatrices one at a time, whereas my improved devices are designed toreverse a plurality of them simultaneously, that is to say, in groups orlines thereof. More specifically speaking, such means are peculiarlydesirable in connection with double or Janus- I faced matrices, such asthose formed with tinguished from the ordinary form of matrlx whereincharacters ar provided on only one edge. Matrices of this descriptionmay thus be employed so that the characters on as fa as their use inthis connection is con-.

cerned, it is immaterial whether ornot the matrices are provided withcharacters on their opposite edges. It will be understood, of course,that when the matrices are to be reversed in the manner above indicated,the characters thereon will be properly arranged and disposed, so thatafter reversal they will be located incorrect osition to form the slugor linot pe, as will be obvious to those familiar wit the art.

My invention is capable of application in numerous forms, and in theaccompanying drawings I have illustrated several different embodimentsby way of example.

. Generally speaking, I desire it to be un derstood that I do not limitmyselfto any specific form or embodiment except in so far as suchlimitations are specified in the claims.

Referring to the drawings: Figure 1 is a front view of the assemblingelevator and connected devices with my invention applied thereto, partlyin section and partly broken.

away to show certain elements more clearly Fig. 2 is a front detail viewon an enlarge scale of the transfer mechanism, the assembler after itsreversal, etc.,- partly broken away; Fig. 2 is-a transverse horizontalsection through the assembler on the line 2 of Fig. 2; Fig. 3 is adetached perspective view of the assembler, and its elevating andreversing means, partly broken away; Fig. 4 is a transverse horizontalsection taken substantially on the line 4 in Fig. 1; Fig. 5 is a partialelevation of the assembler and its reversing means, illustrating amodification; Fig. 6 is a diagrammatic plan view of the same, partlybroken away; Fig. 7 is a detached perspective View of the carriageslide, etc., of the same; Fig. 8 is an end view of the second elevator,and means for transferring the matrices to the' distributor,

7 etc.; Fig. 9 is a corresponding front view thereof; Fig. 10 is a plandetail view of the second elevator, etc.; Fig. 11 is an end view, partlybroken away, of the second elevator and its actuating devices,illustrating a modification; Fig. 12 is a similar View of the secondelevator, etc., illustrating still another modification; and Fig. 13 isa detached detail view of a clutch mechanism to be employed inconnection therewith.

Referring more particularly to Fig. 1, the matrices are delivered in thecustomary way by the manipulation of the keyboard 1 from the magazine tothe belt 3, and from the latter to the star-wheel 4, whereby they areadvanced in the assembler A. Similarly the spacers pass through thedelivery chute 5 tothe star-wheel 4 and then into the assembler. Theseparts are or may be substantially the same as those set forth in thebefore-mentioned Mergenthaler patent. Referring to Figs. 1, 2, 3 and 4,the assembler A is constructed and arranged so that the matricescontained therein may be delivered to the transfer slide E either intheir original or reversed position. Referring to the first mentionedoperation, this is accomplished in the ordinary way by the manipulationof the handle B, whereby the assembler is elevated'and the matricesc011- ta-ined therein delivered bet-ween the downwardly projectingfingers E E and are then shifted laterally as disclosed for instance inthe said Mergenthaler patent.

If it be desired, however, to reverse the position of the assembledline, so that the characters on the rear edges of the matrices will bepresented in the casting position, this is accomplished by turning theassembler through an angle of 180 before the line is delivered to thetransfer fingers E E To this endthe assembler A is provided with theadditional features now to be described. At its lower extremity it hasthe projecting lug A to which'is rigidly connected the downwardlyextending post A? formed near its upper end with the spiral keyway AThis post passes'through the block A fitted to slide horizontally in asuitable guideway A connected to the machine frame, the

movement of which permits the temporary forward withdrawal of theassembler A from its ordinary position in relation to the contiguousparts, and so that it may be turned without interfering therewith. Aspreviously mentioned, the elevation of the assembler is manuallyeffected by the handle B, which is mounted upon the hollow rockshaft Bthe latter being connected by the arm B andthe link B, or in anysuitable manner, to the post A Arranged in contiguity to the handle B isa second handle B, whereby is effected the forward and backward slidingmovementof the block A. The handle B is mounted upon the rock-shaft 13,passing through and contained within the hollow rock-shaft B and aspring B is disposed between the handles B and B,- so that they arenormally held apart. The rock-shaft B is provided with the arm B and alink B connects the arm to the block A", in such manner that themanipulation of the handle B effects the forward and backward slidingmovement of the block A and assembler A connected thereto. After thewithdrawal of the assembler from its normal position, it is elevated bythe handle B and during this upward movement its position is reversed,due to the engagement with the spiral way A of the key D the control ofwhich will be subsequently described.

Before the assembler A can be moved forwardly out of its normalposition, it is necessary that the assembler slide C be disengagedtherefrom. This slide carries the yielding resistant G which advancesbefore the line in course of composition under the influence of thestar-wheel, serving notonly to maintain the line in upright position,but also to shift the transfer finger E all in thesmanner wellunderstood in the art and requiring no further description herein. Theassembler slide C and its connected parts are herein mounted upon andcarried by the plate G which is movably connected to the framework by.means of pivoted links C, C", in such manner that when desired theentire assembling slide mechanism may be moved downwardly from thefull-line to the dotted-line position shown in Fig. 1, thereby freeingthe slide C and the resistant. C from the assembler A and permittingtheadvance of the latter.

In view of the fact that the assembler is reversed end for end, from theposition shown in Fig. 1 to that shown in Fig. 2, the matrices whichpartially fill the assembler are similarly shifted, and before they canpass between the fingers E E the latter must be moved from the full-lineposition of Fig. 1 to that shown in dotted lines therein and in fulllinesiin Fig. 2. This is accomplished automatically in the manner now tobe described. Vhen the parts are disposed for the'normal operationthereof, the transfer slide E and fingen E are held in the extremeright-hand position by the. engagement ofthe pawl E with the shoulder E,the tripping of the pawl E permitting the disengagement of the slide andfinger to transfer the matrices to the first elevator. I also provide apivoted pawl E", which is normally held in its uppermost or inoperativeposition by the spring F], but which when depressed acts by a pin E todisengage the pawl E from the shoulder E and simultaneously engages theshoulder E on the finger E, as the slide E tends tomove the line towardthe'first elevator. When the machine is employed in'l the ordinary way,and without the reversal of the line, the pawl E is disengaged in thecustomary manner and the line is trans ferred directly to the firstelevator and without its being intercepted by the pawl E When, however,the assembler is to be reversed, and consequently the fingers E E haveto be shifted to receive the line in its new position, the pawl E isactuated by the arm D connected to the vertically slidable rod D, aspring D being connected. to the rod so as normally to hold it in itsuppermost or inoperative position. At its lower end the rod is providedwith an arm D which is extended under one end of the pin D, slidablymounted in the bottom of the assembler, the other end of the pin beinglocated in such position as to be depressed and actuated by theassembler slide 0, when the latter is moved downward out of theassembler in the manner previously described and as shown by dottedlines in Fig. l. The depression of the assembler slide t1 thus servesthe double function 'of removing it out of engagement with the assemblerA, and also by its action on the pin D, through the arm D of depressingthe rod D against the force of the spring D and through the arm D ofactuating the pawl E so as to free the pawl E from the shoulder E atwhich time the engagement of the pawl ll with the shoulder E arrests thefingers E and E in proper position to receive the line of matrices, asshown in Fig. 2. When the rod D is thus depressed, it is held by theengagement of the pawl D with the collar D thereon, the parts remainingin this condition until the line is received between the fingers E and Ewhen the elevation of the assembler A brings the projection ll) intocontact with the pawl D and releases it from the collar D The spring Dthen ele vates the rod D and permits the disengage ment of the pawl fromthe shoulder E by the action of the spring E The slide E is now free tocarry the reversed line forward to the first elevator, and the slug iscast in the manner disclosed in the previously mentioned Mergenthalerpatent, Still another function is subscrved by the descent of theassembler slide C and its contact with the pin D, An elbow-lever D ispivotally mounted in the lower portion of the assembler and engages atone end with the pin 1) and at the other end with the key previouslyreferred to. lVhen the pin D is de pressed by the assembler slide C, thelrcy D is projected into the spiral way A in such manner that when theassembler with the post A is moved upwardly, they will be turned throughan angle of 180.

The operation of the parts will now be clearly understood. When it isdesired to send the line forward to the casting mechanism in theordinary way, the handle B is ]'depressed, and through the connectionspreviously described the assembler will be elevated without reversal sothat the line will be received between the fingers E and E which willthen transmit it to the first elevator in the usual manner. Thedepression of the handle B acting on the handle B through the interposedspring 8, and in so far as any rotation of the rock-shaft B is effectedthereby, will tend merely to hold the block A and the assembler A intheir innermost or normal positions. Inother words, the parts when thusoperated will act in exactly the same way as they do in the regularmod-e of operation of a linotype machine.

ll hen it is desired to reverse the assembler and the contained linebefore delivering it to the transfer mechanism, the assembled slide C isfirst lowered to free it from the assembler, and to depress the pin D,thus, inserting the key D into the spiral way A and also through thedepression-of the red I)" and its connected arm' D freeing the pawl Efrom the shoulder E and interposing the pawl E into the path oftheshoulder E, whereby the fingers E and E are brought into proper positionto receive the line in its reversed position. The operator next graspsthe two handles B and B- and presses them together against the force ofthe interposed spring 13 This efiects the partial rotation of therock-shaft B the corresponding forward movement of the slide block A andthe disengagement of the as semble-r A from the contiguous devices. Nextthe operator depresses the handles 13 and 13 together, whereby theassembler A is elevated, and because of the engagement of the key D inthe spiral way A it is given a half turn. Simultaneously with thiselevation and turning of the assembler, the depression of the handle Beffects the turning of the rock-shaft ll and the return or inwardmovement of the slide block A, the parts being so arranged andconstructed that the turning of the assembler and its return to itsnormal vertical plane will be eiiected before the assembler in itsupward travel reaches the finger E, as indicated in Fig. 2. The furtherdepression of the handle B new raises the assembler until the linecontained thereby is received between the lingers ll] and it, when theprojection D acting upon the pawl D releases the rod D and the spring F7elevates the pawl E and permits the transfer slide E to carry thereversed line wardly until it is again inserted in proper relation tothe other assembling devices. These combined turning and inward andoutward movements of the assembler are indicated by dotted lines in Fig.3. As previously described, the pawls E and E have been alreadypermitted to resume their normal positions, due to the rise of the rodD, which similarly elevates the arm D This arm is formed at its innerend with a cam surface D, and as the assembler makes its last or inwardhorizontal movement to norma l position, the pin D is brought intoengagement with this cam surface and is elevated thereby, and thus bythe elbow-lever D withdraws the key D from the spiral way A Theassembler slide C is then elevated, and the parts are again in conditionfor the assemblage of another line. It. is to be noted that so long asthe assembler slide is located in its upper or operative position, theline is transferred in the ordinary man ner, and that only when it isdepressed, are the parts adjusted so that the assembler will bereversed.

The channel in the structed in the usual with means whereby the matricesare held in normal position at the entrance thereof. In ordinaryoperation, the matrices at the other assembler A is conend of the lineare held in correct relation by their contact with the yieldingresistant C and during the upward movement of the assembler, by theirengagement with the finger E When, however, the assembler is reversed inthe manner previously described, the matrices are no longer supported bythe yielding resistant and by the finger, and consequently auxiliarymeans are necessary to that end. These devices (see Fig. 2) consist ofadjustable pawls A A located at opposite sides and projecting into thechannel. The pawls' are provided with extended portions which areslotted to receive the screws A. A, which engage in the sides of theassembler, as for instance in the slots A [i f By these means the pawlsA A. may be adjusted to any length of line desired.

In Figs. 5, 6 and 7, another embodiment of the reversible assembler isillustrated. In this instance the assembler is provided with thedownwardly extending post F, journalcd in the block F which is mountedto slide horizontally in the guide F as in the previous instance. Theguide F is connected to the carriage F, arranged to move upon the way Fwhich guides the assembler vertically to and from the transfer slide. Onthe post-F" are loosely mounted two pinions F and F in position to beacted upon by the racks F and F on the guide F Connected to the pinionsF and F respectively, are two pawls F and F which are so located as toengage the ratchet wheels F form and provided and F keyed upon the postF The slide F may be drawnforward, to permit the assembler to be turned,in the same manner as in the instance already described, but the turningof the assembler is effected by this movement, and not by the elevationof the assembler. As the block F slides forwardly the pinion F engageswith the rack F and is turned thereby, thus similarly causing thepartial rotation of the ratchet-wheel F by the pawl F Simultaneously thepinion F is engaged by the rack F, but due to its location at the otherside of the slide the pawl F rides in the reverse or inoperativedirection over the ratchet-wheel F The parts are so constructed andformed that the outward movement of the block F thus causes the rotationof the post F and the assembler connected thereto through an angle of90, it being further noted that the rack F is so located as to permit ofthe withdrawal of the assembler from its operative position before thepinion F engages therewith. After this'operation the block F is returnedinwardly to its normal position, during which movement the pinion Fengages with the rack F and at which time the simultaneous actuation ofthe pinion F moves the pawl F in the reverse or inoperative direction.The return movement of the block F thus also imparts a rotation of 90 tothe postand assembler, in such manner that when the block and assemblerare restored to normal position, the latter has been turned through anangle of 180, and may be then raised in the ordinary manner to deliverthe line to the transfer slide. This divided rotation of the assemblerand connected parts is indicated by dotted lines in Fig. 6. It ispointed out that the chief distinctions between the present embodimentand the one previously described, are first, that the assembler isturned beforeits elevation, and second, that this turning through 180 iseiiected through 90 during the outward movement of the assembler andthrough the remaining 90 during its return movement. In order to turnthe assembler back to its normal position after its reversal, it isobvious that the cycle of operations just described must be repeated. Ifit be desired to employ the assembler for ordinary purposes and withoutreversing tholine, this may be done by simply omittingthe horizontalto-and-fro sliding movement of the block F -When the groups or lines ofmatrices have been reversed and forwarded to the casting mechanism, theslugs or linotypes are formed in the customary manner, and the matricessubsequently transferred from the first elevator to the secondelevator,by which in turn they are transported to the distributer. meansalso whereby the reversed group or it is obviously desirable to provideeeann line of matrices may be turned through an angle of 180 back totheir original position, before their delivery to the distributingdevices, and to this end I have devised and here illustrate severalmechanisms adapted to effect the desired result. Referring first toFigs. 8, 9 and 10, the matrices are conveyed by the second elevator G tothe up per part of the machine and to such a position that they may bedisengaged therefrom by the line transfer device G and delivered to thedistributer screws G In the form under discussion, the elevator bar G isswiveled upon the ordinary pivoted link G and the link G is providedwith a transverse short shaft G suitably journaled therein, and havingconnected thereto the pinion G and the miter gear G which meshes intoand turns the similar miter gear G connected to the swiveled elevatorbar G. The rack G is mov'ably mounted upon the machine frame, andpreferably as a slide, so that it may be projected into the path of thepinion G, as the second elevator rises and before it reaches itsposition in front of the transfer slide G Suitable means, such as therock-shaft G havingthe arm G and the handle G, are provided so that thesliding rack G may be moved to and from its operative position at will.When the group or line of matrices has been reversed after assemblage,and it is therefore desired to restore them to normal position beforedistribution, the rack G is advanced (see dotted lines Fig. 9), andduring the upward movement of the elevator (see dotted lines Fig. 8) thepinion G engages with the rack,

and as a result thereof the elevator bar G is turned (see dotted linesFig. 10), before it reaches its operative position shown by full linesin Fig. 8. v

lnFig. 11 l have shown another mechanish for effecting a similarturningof the second elevator bar. in this instance the bar H has also aswiveling connection with the elevator lever H which is acted u on inthe well-known manner by the cam H so as to raise the bar from theposition shown in full lines to the one shown in dotted lines. Connectedto the swiveling bar H is a drum H provided with a chain or otherflexible connection H, which passes about suitable rolls upon theelevator arm H and is connected to the end of the supplemental lever Hpivotally mounted upon the main frame. The leverl-l is acted upon by thecam section 1-1 so shaped and located upon the elevator cam 1-1", thatduring the upward movement of the elevator, through the flexibleconnection H and drum H the bar H is rotated through an angle of 180 inthe manner before described.

In Figs. 12 and 13 l have illustrated still another modification forsecuring a similar turning of the elevator bar J, which has a swivelingconnection with the elevator arm 5 and is raised to its uppermostposition by the elevator cam 5 In this instance, the swiveling bar J isalso provided with a drum J and a flexible connection J which passesdownwardly and is connected to a drum J mounted upon the short shaft Jsuitably journalcd in the main frame. Also mounted upon the shaft J is asecond drum J, of smaller diameter than the drum J and from the drum Jpasses a second flexible connection 5 to the end of the elevator lever Jwhich is in proximity to the cam. As the lever J is moved by the cam Jthe flexible connection J rotates the drum 5', effecting also therotation of the drum J and because of the greater leverage thereofarising from the difference in diameter of the two drums, the connectionJ acting upon the drum J eficcts the turning of the elevator bar 5through an angle of 180, In order to per mit the connection anddisconnection of these turning means at will, I have provided aclutching device which is illustrated in Fig. 13. The drum J is looselymounted upon the shaft J, and the drum J is rigidly connected thereto.In order to permit the connection and disconnection of the looselymounted drum J I provide a clutch member J slidably mounted but keyed tothe shaft 6 and adapted to be engaged with. the drum J 5 at will. Forthe purpose of shifting the clutch member J I may employ any suitableactuating device, such as the sliding member J.

l have described the foregoing mechanisms simply as preferred forms ofthe embodiment of my invention, and obviously many changes andvariations may be made therein without departing from its spirit, thebroad underlying feature of which is the turning and reversing of anassembled group or line of matrices end for end before casting, and Ibelieve this is to be broadly new.
